In Laravel, Middleware is ignored in ajax request?

This is the method in controller. It is requested by x-editable ajax.

/**
 * Update base info such as status.
 *
 * @param Request $request
 * @return mixed
 */
public function postUpdateInfo(Request $request)
{
    $this->middleware('recruit');
    dd('passed');
    $recruit = Recruit::find($request->get('pk'));
    list($key, $value) = array($request->get('name'), $request->get('value'));
    if ($recruit->update([$key => $value])) {
        return Response::json(['success' => 1]);
    }
}

In middleware, codes below:

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request $request
 * @param  \Closure $next
 * @return mixed
 */
public function handle($request, Closure $next, $permission)
{
    die();
    if (Entrust::can($permission)) {
        return $next($request);
    }

    $this->belongsToMe($request, $this->instance);

    return $next($request);
}

But in chrome, I view the response in network.

So, I think middleware is ignored in ajax request? So amazing.

Thanks a lot.
